Meghan Markle, as she was then named, didn’t appreciate the formality of British royal life until, being driven to meet the Queen for the first time, at Prince Andrew’s residence west of London, boyfriend Prince Harry asked if she knew how to curtsy.

“That’s the first moment that the penny dropped that this wasn’t easy for me,” the Duchess of Sussex told American television host Oprah Winfrey in an interview broadcast on Monday. “Apparently I did a very deep curtsy.”
